A case of osteoarthritis of the knee accompanied by ipsilateral osteoarthritic ankle was reported. The patient was a 67-year-old woman who suffered from osteoarthritis of the right knee and right ankle. Radiographs showed osteoarthritic change Grade 3 (Yokohama City University grading) in the knee and stage 4 (Nara staging) in the ankle. To treat severe varus deformity of the knee, high tibial osteotomy was performed. Total ankle arthroplasty was done six months after the initial high tibial osteotomy. Two and a half years after ankle surgery, patient has little difficulty in activities of daily living. The Japanese Orthopaedic Association score for the knee improved from 65 points before surgeries to 85 points after surgeries, and that for the ankle from 48 to 77 points. For patients suffering from double joint osteoarthritis in the same leg, clinical results indicate that it may be important to correct the alignment of the knee before total ankle arthroplasty.
